Identity and Individuation in Kant’s Transcendental Deduction
(DRAFT)
Jacqueline Mariña
In this paper, I offer a reconstruction of the B-edition of Kant’s
Transcendental Deduction in terms of what Dieter Henrich has termed an
“identity deduction,”i namely, an analysis of the conditions of the possibility
for cognizing the “I think” necessary for both concept formation and
judgment. On this reading, a significant aim of the transcendental deduction
(TD) is to show that only through an a priori transcendental employment of
the categories can the “I think” be determined at all. Hence, such an a priori
transcendental employment must be presupposed for even the most
rudimentary empirical judgments to be possible. Such an analysis of the TD,
as one whose fundamental problem is the establishment of the conditions of
the possibility of self-consciousness, is consistent with viewing the B-edition
version of the deduction as a single proof in two steps:ii as such, it can be
shown that the conclusion arrived at in § 20, and that arrived at in § 26, both
pertain in crucial ways to the conditions of the possibility of self-
consciousness. Kant’s argument first establishes that if judgment is to be
possible at all, we must be able to cognize an “I think” that accompanies all
my representations. Cognizing such an I think, is, however, highly
problematic The Deduction then shows that cognition of the “I think” is only
possible through a transcendental employment of the categories. Such a
transcendental employment involves two elements, treated in each of the
two steps of the TD. In the first, Kant discusses the logical function of the
categories. In the second, the all-important role of space and time and the
transcendental unity furnished to them by the categories is discussed as
integral to generating the “I think.” Whether or not this argumentative
strategy is fully successful, following its contours will prove extremely fruitful
in understanding Kant’s notion of the self.iii
Apperception and the “I think”
1
In § 15, Kant tells us that a) the possibility of analysis presupposes a
prior synthesis, for “where the understanding has not previously combined
anything, neither can it dissolve anything” and b) all combination and
synthesis presupposes a prior unity. At this point in the deduction, the
nature of neither this synthesis nor the prior unity has been made explicit.
Nevertheless, it introduces the key problem of the deduction, namely, the
nature of the unity grounding all acts of judgment. §16 provides an
examination of how this unity must function if combination is to be possible.
Before Kant discusses how this unity must function, however, he makes an
important distinction central to the problem of the deduction, namely that
between original apperception and the representation “I think.” He notes
that original apperception produces the representation I think. How original
apperception produces the representation I think is a key feature of the
deduction.
The Function of the I think in Judgment
Kant tells us that that the unity of the I think is the “transcendental
unity of self-consciousness.” Through the representation I think the self is
conscious of itself, that is, becomes an object for itself. At the beginning of
the §16 Kant notes that “The I think must be able to accompany all my
representations; for otherwise something would be represented in me that
could not be thought at all, which is as much to say that the representation
would either be impossible or at least would be nothing for me.” If a
representation is to function as a representation, I must be able to
distinguish this representation from myself (as she who is having the
representation);iv moreover, I must be able to distinguish the representation
from the object it represents. In order for it to be possible to make this
distinction a) the self must become its own object, b) it must be possible to
identify the self as different from the representation (and this means both
self and representation must be able to become objects of consciousness
and c) it must be possible to identify the self as that which remains identical
2
throughout changes in its representations. Without the ability of self-
consciousness to accompany such representations, one might very well be
able to feel, but not to think. Hence a sea sponge might, for instance, feel
the hotness of a current, but it would not be conscious of itself as different
from this current, nor would it be conscious of the heat as a characteristic of
the water surrounding it.
i See Dieter Henrich, “Identity and Objectivity,” in The Unity of Reason:
Essays on Kant’s Philosophy, Cambridge: Harvard University Press, 1994,
especially section III, “Identity and Self-Consciousness.” ii Dieter Henrich’s important article “The Proof Structure of Kant’s
Transcendental Deduction” details a significant problem commentators have
noted with the deduction, namely that the conclusion of §20: “Consequently,
the manifold in a given intution is necessarily subject to the categories”
(B145) does note seem to differ significantly from the result of §26: “the
categories. . . are valid . . . a priori for all objects of experience” (B 161).
Against older commentaries such as those by Paton, Adickes, Erdmann, and
de Vleeshauwer, who read the text as two distinct and complete proofs for
the TD, I am in agreement with Henrich’s proposal taking Kant at his word
that §20 and §26 offer two arguments with differing results constituting a
single proof of the TD. In Kant on Pure Reason, Oxford: Oxford University
Press, 1982. My own interpretation relates the results of §20 and §26 to an
analysis of the conditions of the possibility of self-consciousness. iii There have been many recent fine studies of Kant’s understanding of the
self; I note only a few of them here. Karl Ameriks, Michelle Grier, and Heiner
Klemme have written insightful accounts of Kant’s critique of rational
psychology: Karl Ameriks, Kant’s Theory of Mind: An Analysis of the
Paralogisms of Pure Reason, 2nd edn., Oxford: Clarendon Press, 2000;

Kant next asks: under what conditions can such representations stand
together in a universal self-consciousness? How are we to characterize this
consciousness of self that must accompany each representation? Because
this consciousness is one and the same, it cannot be accompanied by any
further representations. As such, the empirical consciousness of the self that
accompanies different representations, which “is itself dispersed and without
relation to the identity of the subject” (B 133), will not do the trick. This
empirical consciousness is the consciousness I have of myself as an
embodied being in the world. I have such a consciousness of myself insofar
as I can sense myself and make myself my own object: I see my hands, I
recognize myself in the mirror, hear myself, and so forth. This consciousness
of self depends on what is given to the senses. It must be distinguished from
a transcendental consciousness of myself, which I have a priori. The
representation of the empirical self is complex: it is a subject with many
characteristics (the subject is “dispersed”). Moreover, the empirical self is

iv As both Allison and Longuenesse have correctly noted, Kant is not here
denying that one cannot have mental states of which one cannot be
conscious. However, in order for such states to function cognitively as
representations, the self must be able to be conscious of them as being
representations, which is to say it must represent itself as having them. See

constantly changing. Hence this representation lacks the simplicity and
stable identity required for the I think that must accompany each of my
representations. We are still, therefore, at a loss to understand how this I
think is to be determined.
Kant next notes, “this thoroughgoing identity of the apperception of a
manifold given in intuition contains a synthesis of representations, and is
possible only through the consciousness of this synthesis.” There is much
that is puzzling here. For one, in §15 Kant noted that we needed to seek
“that which itself contains the ground of the unity of different concepts in
judgments, and hence the possibility of the understanding, even in its logical
use.” But here he seems to be claiming that the identity of apperception is
itself only possible through consciousness of the synthesis of
representations. As such, either Kant is confused, or the identity of
apperception cannot be the ground of the unity of different concepts in
judgments, since identity only results through consciousness of the synthesis
of representations. The identity of apperception must therefore be
distinguished from original apperception, which does ground the unity of
different concepts in judgments. The unity of original apperception already
implies a synthesis of the manifold, but it is only through consciousness of
this synthesis that the identity of apperception is achieved. Hence the unity
of original apperception grounds both the synthesis of the manifold and the
identity of apperception. Only through the action of original apperception in
generating the manifold can original apperception ground both the synthesis
of the manifold and the identity of apperception. Kant notes that the identity
of the subject “does not yet come about by my accompanying each
representation with consciousness, but rather by my adding one
representation to the other and being conscious of their synthesis” (B 133).
The synthesis that is generated through the addition of one representation to
another (a synthesis of the imagination) must be presupposed if identity of
consciousness is to be achieved. This is what Kant means when he notes
that “it is only because I can combine a manifold of given representations in
5
one consciousness that it is possible for me to represent the identity of
the consciousness in these representations itself, i.e., the analytical
unity of apperception is only possible under some synthetic one” (B133).
This combination is achieved through the blind power of the imagination; this
is not a self-conscious synthesis.v The unity provided by the imagination in
the generation of the manifold must be presupposed if analysis through the
use of concepts can be achieved. In the important footnote to B 133, he
notes that
The analytical unity of consciousness pertains to all common
concepts as such, e.g., if I think of red in general, I thereby
represent to myself a feature that (as a mark) can be
encountered in anything, or that can be combined with other
representations; therefore only by means of an antecedently
conceived possible synthetic unity can I represent to myself the
analytical unity. A representation that is to be thought of as
common to several must be regarded as belonging to those that
in addition to it also have something different in themselves;
consequently they must antecedently be conceived in synthetic
unity with other (even if only possible representations) before I
v On this point I stand in agreement with Longuenesse, who distinguishes
between a sensible synthesis and a synthesis of concepts. The sensible
synthesis is a necessary condition for the synthesis of concepts.
Commenting on B135-36, she notes, “If it is hard to see how representations,
on the one hand, stand under a “necessary a priori synthesis,” and on the
other hand also have to be brought under this synthesis, consider that
synthesis is, on the one hand, synthesis of the manifold “as” sensible
manifold and, on the other hand, a discursive synthesis by which this
manifold is reflected under concepts. The latter is possible only under the
condition of the former, and conversely, the former is oriented toward
achieving the latter” Longueness, 68.

can think of the analytical unity of consciousness in that it makes
it into a conceptus communis (B133n).
A concept is a general representation: through it many representations can
be thought under a common mark. But in order for the concept to function
in such a way, I must be able to think of several possible representations,
differentiated from one another but yet sharing a common mark, as standing
under it. These representations must be held together if I am to think them
under a concept (the common mark that they all share). This holding
together of these representations is a synthesis; for these reasons “the
synthetic unity of apperception is the highest point to which one must affix
all use of the understanding.” However, insofar as this synthesis remains
one of the imagination only, it is a necessary but not a sufficient condition for
the analytical unity of consciousness.
Now, this analytical unity must be presupposed if representations are
to function as concepts: it is “the analytical unity of consciousness [in a
general representation] that makes it into a conceptus commmunis] (B
134n). In other words, if I am to think of a mark as common to several
representations, I must be able to know that it is the same I that grasps each
of these representations individually, reproduces and recognizes the mark
common to them all (in fact the identity of the I is presupposed in each of
these activities). The analytical unity of consciousness thus stands in the
closest possible unity to the I think. In fact, it refers to the principle function
of the I think in the use of concepts in judgments.vi Discursive thought,
through which many representations are brought under a common concept,
presupposes the possibility of recognition of the identity of the I think, and
thus self-consciousness. This simply expands upon what is said at the
beginning of §16: “The I think must be able to accompany all my
representations;” only in such a way can I call them mine. In order for the
self to recognize representations as its own, it must be possible for it to
become conscious of itself as the I that has multiple representations: “The
7
thought that these representation given in intuition all together belong to
me means, accordingly, the same as that I unite them in a self-
consciousness, or at least can unity them therein….” B134 (Italics mine).
The problem still remains: how, if self-consciousness is a condition of
the possibility of thinking, is this self-consciousness to be cognized? We
noted that some synthetic unity of consciousness is a necessary condition for
the analytic unity. However, it is still not clear how such an analytic unity is
possible: how are we to cognize the identity of the self in its acts of
apprehending, reproducing, and recognizing representations? Such a
cognition of the identity of the self throughout its having different
representations is a necessary condition for self-consciousness.
Understanding how this cognition is possible is made especially difficult by
the fact that the identity of self-consciousness has no manifold of its own and
therefore no content through which it can be cognized. Kant notes that
“through the I, as a simple representation, nothing manifold is given; it [the
manifold] can only be given in the intuition, which is distinct from it, and
thought through combination in a consciousness.”vii If the simple
representation I has no content, then it contains no distinguishing marks
through which it can be picked out and identified. As Henrich notes, here
Kant cannot go the route of Leibniz, for whom the representational states are
incorporated into the essence of the subject: for Kant these states are given
in intuition and determined by something different from the subject, and
hence are not part of the subject.viii Kant contrasts the nature of a discursive
understanding that can only think with one in which through self-
consciousness the manifold would at the same time be given. It is this
peculiar nature of our discursive understanding that motivates the central
problem of the B-deduction, namely, how self-consciousness is possible
given that the representation I think has no content. Here we would do well
also to recall Kant’s earlier discussion that the I think should not be confused
with an empirical representation of the self, which does not remain identical
through time and does not accompany all my representations.
8
What, then is it about the simple representation I that allows it to be
identified as the same through different acts of thought? Kant’s solution is to
argue that since the I itself has no manifold, the identity of the I can only be
given in the unity of the representations of the self.
I am therefore conscious of the identical self in regard to the manifold of the representations that are given to me in an intuition because I call them all together my representations, which constitute one. But that is as much to say that I am conscious of their necessary synthesis, which is called the original unity of apperception, under which all representations given to me stand, but under which they must also be brought by means of a synthesis (B 135).
Synthetic unity is a sufficient condition for the identity of the I think. This
unity, however, is not just the unity of a bundle of representations, à la
Hume. That kind of unity will not help in determining the I and ensuring that I
can become self-consciously aware of myself as the same I in my transition
from one representation to the next. On this model the representation of the
I remains just as empty and indeterminate as before, since it is just that
which holds together the representations as a unity: it is still an empty
vi Allison notes that the “identical I think, that is, ‘the bare representations I,”
can be seen as the form or prototype of the analytic unity that pertains to all
general concepts. In fact, it just is this analytic unity considered in
abstraction from all content. Consequently, the I think is itself the thought of
what is common to all conceptualization, which is what makes it “in all
consciousness one and the same (B132).” Kant’s Transcendental Idealism,
172. Allison is too quick to identify the I think with the analytic unity. While
it is certainly the case that the analytic unity of the concept is made possible
by identity of the I think, the I think is not fully determinable by its function
of making possible the analytic unity of a concept. Certainly the ability to
range distinct concepts under a more general one presupposes the identity
of the I think, but it does not, by itself allow us determine the identity of the I
think throughout different acts of conceptualization. For this something
more is required, and this is the subject matter of the second part of the TD.

placeholder. Given these constraints, the only way left to identify the I (and
for the I to become conscious of itself) is through its activity in synthesizing
the representations that are given to it. But I can only become conscious of
this activity through its results, namely the synthesis of representations.
Hence if Kant is correct, he will have shown that this synthesis is a sufficient
condition for determining the I think, and the problem of §16–how
determination of the I think is possible–will be solved.
Much work remains to be done, however. Granted that identity of the
self is achieved through the way in which the I relates the representations to
one another, Kant still needs to show that only if the self relates these
representations to one another in accordance with given rules (the
categories) will it be possible for the self to become conscious of itself. In
other words, he needs to show that only if there is a given blueprint for how
representations are to be related to one another in the concept of the object
is self-consciousness possible. This means: a necessary condition for
consciousness of the identity of the self is the capacity for determining the
relation of representations to one another (in the concept of the object) in
accordance with given rules; only such a rules can guarantee the unity of
representations. This much stronger claim is of course what Kant needs if he
is to show that the categories must be presupposed if thinking and judgment
is to be possible at all. He needs to demonstrate: I can only become
conscious of the identical activity of thought if this activity occurs in
accordance with necessary rules for the synthesis of the manifold. This is
what is behind the very important passage at A 108:
For this unity of consciousness would be impossible if in the cognition of the manifold the mind could not become conscious of the identity of the function by means of which this manifold is synthetically combined into one cognition. Thus the original and necessary consciousness of the identity of oneself is at the same time a consciousness of an equally necessary unity of the synthesis of all appearances in accordance with concepts, i.e., in accordance with rules that not only make them necessarily reproducible, but also thereby determine an object for their intuition, i.e., the concept of something in which they are
10
necessarily connected; for the mind could not possibly think of the identity of itself in the manifoldness of its representations, and indeed think this a priori, if it did not have before its eyes the identity of its action, which subjects all synthesis of apprehension (which is empirical) to a transcendental unity, and first makes possible their connection in accordance with a priori rules (A 108).
If the self is to become conscious of itself as identical through a
consciousness of its activity, then this activity must be recognizable through
the rules of its operation. Two points are important here. First, how self-
consciousness operates can only be known through what it produces, namely
the specification of the relation of representations to one another (the
synthesis of the manifold). Second, these rules specifying the necessary
vii In the famous chapter on personal identity in his Treatise, Hume had
already noted that we do not have an “any idea of self.” He asks, “For from
what impression could this idea be derived? . . . . It must be some one
impression that gives rise to every real idea. But self or person is not any
one impression, but that to which our several impressions and ideas are
supposed to have a reference. If any impression gives rise to the idea of
self, that impression must continue invariably the same throughout the
whole course of our lives, since self is supposed to exist after that manner.
But there is no impression constant and invariable. Pain and pleasure, grief
and joy, passions and sensations succeed each other and never all exist at
the same time. It cannot, therefore, be from any of these impressions or
from any other that the idea of self is derived, and consequently, there is no
such idea. . . . For my part, when I enter most intimately into what I call
myself, I always stumble on some particular perception or other, of heat or
cold, light or shade, love or hatred, pain or pleasure. I never can catch
myself at any time without a perception and can never observe anything but
the perception. . . . “ David Hume, A Treatise of Human Nature, edited by L.

relation of representations to one another supply a map, so to speak, from
any given representation to another representation. The rules guarantee the
availability of a representation on the condition that another is given; only
thereby can such a representation stand under the unity given through the
synthesis.ix As such, only given necessary rules for the synthesis of
representations (the categories) is it possible to guarantee that
representations stand under the unity of the I think. The gist of the
argument can be simplified in the following way: how can you identify a
number representations as belonging to the same set (the set of my
representations) if there is no straightforward way of identifying the common
mark under which they can be subsumed, namely, that they belong to the
same I that thinks them? Recall that the bare representation I contains no
manifold. Under such conditions, their belonging to the same set (the set of
my representations) can only be determined by an activity of consciousness
in accordance with necessary rules. Such rules guarantee the availability of
a representation on the condition that another is given; only if a
representation is available in this way does it stand under the unity of
consciousness. Such rules thereby function to bring the representations to a
unity; this synthetic unity is what guarantees that I can call them all together
my representations. The unity of consciousness is thereby cognized through
its activity and its result, which is the form (the set of relations) of a set of
representations.
Given what has been argued thus far, in §17 Kant brings in the notion
of an object: an object is “that in the concept of which the manifold of a
given intuition is united.” The concept of the object supplies the rule
through which to relate representations to one another. A similar idea is put
forward in an important passage in the A-Deduction, where Kant notes:
But these appearances are not things in themselves; they are only representations, which in turn have their object–an object which cannot itself be intuited by us, and which may, therefore, be named the non-empirical, that is, transcendental object = X.
12
The pure concept of this transcendental object, which in reality throughout all our knowledge is one and the same, is what can alone confer upon all our empirical concepts in general relation to an object, that is, objective reality. This concept cannot contain any determinate intuition, and therefore refers only to that unity which must be met with in any manifold of cognition [Erkenntnis] which stands in relation to an object. This relation is nothing but the necessary unity of consciousness, and therefore also of the synthesis of the manifold, through a common function of the mind, which combines it in one representation (A 109).
Not only does the concept of the object supply the rule through which to
relate representations to one another, the object is that to which
representations refer. As such, the transcendental object is never given in
any particular representation, since no single representation can be
adequate to it. Rather, different apprehensions or representations can be
representations of the same object, each representation revealing a different
aspect or characteristic of the object. This transcendental object, to which
all representations having objective validity must be referred, has a given
structure. Representations referring to it must hook up with other
representations referring to it in specific ways. Only if representations are
structured in accordance with a certain rule is cognition of the object
possible. Hence the necessary form or structure supplied by the
understanding to a manifold of representations is given with the concept of
the transcendental object.x Insofar as the transcendental object specifies of
the relation of parts of the manifold of appearance to one another, it is not
ix Henrich puts forward a similar idea: “Something is the representational
state, and thus likewise the representational content, of one subject only
when it is known as that to which advancement can be made starting from
every representational content…. Modes and rules must already be in place
by virtue of which each representational content can be the content of a
representational state in a way that permits a transition to be made from it
to every other content while it maintains its own determinateness” Henrich,
190.
13
itself intuitable; it is only given through the function of the understanding
that relates the parts of the manifold to one another and refers such
representations to the transcendental object.xi The pure concept of the
transcendental object functions in two ways: a) it is that to which
representations are referred and b) it supplies the rule specifying the way
that representations must be related to one another if judgment about an
object is to be possible.
Rules specifying the way that representations are to be related to one
another stem from a common function of the mind, namely the necessary
unity of consciousness. This is what Kant means when he tells us that “the
unity of consciousness is that which alone constitutes the relation of
representations to an object, thus their objective validity….” (B 137). The
rules generated by this common and original function of the mind are the
rules for the synthesis of the manifold that must be presupposed if judgment
is to be possible at all.xii That these operations of synthesis are a necessary
condition for the unification of representations under one consciousness is,
according to Kant, an analytic proposition. If an intuition is to be an object
for me, it must stand under rules of synthesis: “The synthetic unity of
consciousness…..is rather something under which every intuition must stand
in order to become an object for me, since in any other way, and without this
synthesis, the object would not be united in one consciousness” (B 138).
Given that the whole TD is about the nature of a discursive, and not an
intuitive intellect, it goes without saying that the representations thus
related are given to understanding in intuition. Nevertheless, the synthesis
Kant has in mind at §17 is a purely logical one; it specifies the relation
between representations (and thereby generates the logical object). Here
the original synthesis is being considered in abstraction from the forms of
intuition through which intuitions are given.xiii Hence the original synthetic
unity of apperception producing the logical object characterizes all discursive
intellects, including discursive intellects whose forms of intuition are different
from our own. This is what Kant means when he says that the “synthetic
14
unity of consciousness is therefore an objective condition of all cognition, not
merely something I myself need in order to cognize an object….” (B 138).
The synthetic unity of consciousness pertains analytically to all discursive
intellects, that is, contained in the concept of a discursive intellect is the
principle that I can only become conscious that a representation is mine if
that representation is subject to certain logical rules. As Kant notes at the
end of §17, this principle does not hold for all possible understandings:
But only for one through whose pure apperception in the representation I am nothing manifold is given at all. That understanding through whose self-consciousness the manifold of intuition would at the same time be given, an understanding through whose representations the objects of this representation would at the same time exist, would not require a special act of the synthesis of the manifold for the unity of consciousness, which the human understanding, which merely thinks, but does not intuit, does require (B 139).
The analytic principle that unity among representations can only be achieved
through their synthesis holds only for a discursive intellect that does not
produce its own manifold, but operates on one given to it from a source
outside itself. Given that the I think has no manifold of its own,
consciousness of the identical self can be achieved only through the unity of
representations that I can all together call my representations.
Empirical Consciousness and the Subjective Unity of Apperception
In §18 Kant takes up the problem of what he calls the subjective unity.
This is the unity assumed by Hume in his association of ideas: according to
Hume, we make judgments, such as the judgment “x causes y” because we
have found x and y to be constantly conjoined in our consciousness. This
constant conjunction leads us to associate the representation x with the
representation y, and to expect the occurrence of y once x is given. The
notion of constant conjunction presupposes, however, that we have direct
access to the order of representations as they appear in consciousness, and
that it is this order that can ground the kinds of associations between
representations necessary for judgments. Three main points are made here,
15
all important for the way that Kant contrasts the empirical self with the
identity of apperception. First, the subjective unity of apperception, namely,
the order of representations as they are given to consciousness and
associated with one another will not guarantee the unity of representations
necessary to determine the I think. Second, and closely related to the first
point: since the I think is a precondition for the subordination of concepts
that occurs in any act of judgment, judgment is impossible through a
x In Reflexion 6350, Kant writes: “What is an object? That which is
represented through a totality of several predicates which pertain to it. The
plate is round, warm, tin, etc. ‘Warm’, ‘round’, ‘tin’, etc., are not objects, but
the warmth, the tin, etc. are. An object is that in the representation of which
other representations can be thought as synthetically connected. Every
judgment has a subject and predicate. The subject of the judgment, insofar
as it contains different possible predicates, is the object” (Ak. XVIII, 676; cf.
Longuenesse, Capacity, 55, Henrich, Identity, 152, Allison, Idealism, 146-47
(first edition). Here a similar, although not identical thought to the passage
at A 109, is expressed. The idea of the object is that in which a synthesis of
representations in accordance with a rule can be thought. As such, insofar
as a representation stands for an object, it can function as the subject of a
judgment, which can then stand under many possible predicates.
xi Longuenesse notes that the transcendental object “is not itself a
representation any more” (Longuenesse, Capacity, 54). Such a
characterization can be misleading, since it does not capture the essential
function of the transcendental object. The transcendental object is not
intuitable, because it is that in the concept of which representations can be
united in such a way that judgment is possible. While the transcendental
object is itself not intuitable, it is represented whenever a representation
stands for an object directly. At least that is what is suggested by Reflexion
6350, cited above, where Kant notes that “the subject of the judgment,
insofar as it contains different possible predicates, is the object.” Here we
16
subjective unity alone. Third, in any case, determination of the order of
representations as they are given to consciousness in the subjective unity
presupposes the objective unity of consciousness.
Kant defines the subjective unity of consciousness as a “determination
of inner sense, through which that manifold of intuition is empirically given
for such a combination (B 139). The order in which I initially apprehend
representations contains no necessity. It can be conditioned by many
factors. For instance, I may associate one representation with another due
to unconscious forces, hence my having one representation may lead me to
have another. Or the particular order in which I apprehend parts of a
manifold may be affected by how attentive or inattentive I am to my
surroundings at a particular moment. Hence this order of apprehension is
only given empirically, that is, it is not determinable a priori but only after
the representations have in fact appeared in inner sense. Since this
empirical unity is not governed by a priori rules, there is no necessity to it:
“One person combines the representation of a certain word with one thing,
another with something else; and the unity of consciousness in that which is
empirical is not, with regard to that which is given, necessarily and
universally valid” (B140). However, not only are there differences to how
have a representation that functions as the subject of a judgment through
indicating the transcendental object.
xii Longuenesse has rightly stressed the importance of Kant’s assertion that
“the same function that gives unity to different representations in a
judgment also gives unity to the mere synthesis of different representations
in an intuition….(A 79/B104-5). She shows, convincingly, to my mind, that
Kant’s table of logical forms “can only have emerged from Kant’s painstaking
reflections about the relation between the forms according to which we
relate concepts to other concepts, and thus to objects…and forms according
to which we may combine manifolds in intuition so that they may fall under
concepts….”(Companion, 146).

distinct individuals will associate representations, (hence how those
representations will appear in inner sense), but there are differences in how
a single individual associates representations across different swaths of time.
Hence at one moment I may associate blue with the summer sky, and at
another time I may associate it with jazz. Mere association, therefore, does
not prescribe a given order to representations, and hence does not provide
me with a way of accessing any given representation on the condition that
another has been given. Without such a given order, I am not in a position to
grasp a representation as mine, and hence to arrive at a unity of experience.
But without such a unity of experience, determination of the identity of the I
think is impossible. This means, further, that if all we had were a mere
subjective unity, judgment would be impossible.
However, as Kant is quick to point out we are never conscious of only a
subjective unity, for such consciousness of subjective unity presupposes and
is grounded in an objective unity. Kant notes that the “empirical unity of
apperception….is also derived only from the former [the pure synthesis of
the understanding], which is “alone objectively valid;” hence the pure
synthesis of the understanding “grounds a priori the empirical synthesis
(B140).” He argues for the claim very briefly, noting that in order for me to
apprehend an intuition, it must be given through some form of intuition (in
our case, time). However, as a form of intuition, time can only stand under
the original unity of consciousness through its relation to the one I think, and
hence through the pure synthesis of the understanding. Time itself must
therefore stand under an a priori synthesis, and only given this
xiii This is what Kant means when he notes that the “first pure cognition of the
understanding, therefore, on which the whole of the reset of its use is
grounded, and that is at the same time also entirely independent from all
conditions of sensible intuition, is the principle of the original synthetic unity
of apperception” B 137). On this point see Longuenesse, 69ff., Allison, 173-
185,
18
transcendental synthesis is an empirical synthesis even possible at all. This
is by far the most important point in §18, and it corresponds, in part, to the
points Kant makes in his A-deduction analysis of the threefold synthesis.
Given that in the first part of the B-deduction Kant attempts to abstract from
the conditions of our sensibility, this discussion in A already anticipates some
of the conclusions that would only be fully established in the latter part of
the B-deduction. Nevertheless, Kant’s point in §18 cannot be fully grasped
without understanding where the argument leads, and this is illuminated by
the discussion of the threefold synthesis in A.
There Kant also argued, albeit in much more detail, that the empirical
synthesis of reproduction through which we apprehend and associate
empirically given elements of the manifold presupposes a pure synthesis of
the manifold (in the case of our own cognition a synthesis of time as the
form or our intuition). In an often misunderstood passages of the A-
deduction, Kant notes that
If cinnabar were now red, now black, now light, now heavy, if a human being were now changed into this animal shape, now into that one, if on the longest day the land were covered with fruits, now with ice and snow, then my empirical imagination would never even get to think of heavy cinnabar on the occasion of the representation of the color red; or if a certain word were attributed now to this thing, now to that, or if one and the same thing were sometimes called this, sometimes that, without the governance of a certain rule to which the appearances are already subjected in themselves, then no empirical synthesis of reproduction could take place (A 101).
The discussion that follows is an examination of the conditions necessary for
me to be able to reproduce representations; nowhere does Kant claim his
discussion of the threefold synthesis examines the conditions sufficient for
the reproducibility of empirical representations. The upshot of this
discussion is that were the mind to be unaware of the identity of its act in
thinking different representations, it could not identify a representation as
the same one that it thought a moment before. In such a case the utmost
confusion would result, and my concept of cinnabar would at one moment be
19
associated with red, then with black, and so forth, for I would have no way of
recalling what it was I had thought a moment before. This is because I would
have no determination of an “I think” to which I could even link past
representations. As I will make clear, Kant’s point here is that a figurative
synthesis is a necessary condition for the ability to identify what I think now
with what I thought a moment before.
While the problem Kant draws attention to regarding the
reproducibility of representations occurs in his discussion of part two of the
threefold synthesis, the three kinds of synthesis are really distinct moments
of the act of recognition in a concept. In order to apprehend I must
reproduce, and in order for the act of reproduction to have any point I must
be able to recognize what I reproduced in a concept. Only if such a threefold
synthesis is presupposed can there be any way for me to identify that the
representation I have now is the same one that I had a moment before, and
only if I can re-identify representations will it be possible for me to
successfully become conscious of their association.
Key to Kant’s whole discussion is the way that elements of a manifold
are apprehended: a manifold would “not be represented as such if the mind
did not distinguish the time in the succession of impressions on one another;
for as contained in one moment no representation can ever be anything than
absolute unity” (A99). The manifold, as manifold, contains many elements
that must be run through and held together. How can this happen? Only if
in running them through I can also reproduce them, for without such
reproduction of what has been apprehended before, I could never hold all the
elements together. But what is it that makes possible the empirical
reproduction of representations? This is the key question. Empirical
reproduction presupposes “a combination of the manifold that makes
possible a thoroughgoing synthesis of reproduction.” This is a pure
transcendental synthesis of the imagination, and what is combined in this
pure synthesis is time as the formal condition of inner sense, which is that in
which all representations “must all be ordered, connected, and brought into
20
relations” (A99). Now the only way a representation could be reproduced a
priori is if I knew ahead of time what it is that must be reproduced, and I can
only do that if what is being reproduced is always the same. Given that the
parts of space and time are homogenous, their units can be reproduced
ahead of time through their production by the imagination. Hence their
reproduction is really a productive synthesis of the imagination: the
imagination can both produce the form of what has been given before and
anticipate the form of what is yet to be given through the mere addition of
the homogeneous units, namely space and time. This is a figurative
synthesis, and this is why the example that Kant brings up at A102 has to do
with precisely such a synthesis:
Now it is obvious that if I draw a line in thought, or think of the time from one noon to the next, or even want to represent a certain number to myself, I must necessarily first grasp one of these manifold representations after another in my thoughts. But if I were always to lose the preceding representations (the first part of the line, the preceding parts of time, or the successively represented units) from my thoughts and not reproduce them when I proceed to the following ones, then no whole representation and none of the previously mentioned thoughts, not even the purest and most fundamental representations of space and time, could ever arise. The synthesis of apprehension is therefore inseparably connected with the synthesis of reproduction (A102).
Kant’s point is that this production of the units of space and time by the
imagination (which is an apriori act of the understanding upon the form of
intuition) is a necessary condition for me to have a whole representation of a
given manifold, without which any kind of cognition would be impossible at
all. In order to have such a whole representation, I must be able to retain a
preceding representation in mind and reproduce it when necessary: if I
cannot do that, no synthesis, and therefore no complete representation, is
possible at all. Indeed, all I would have is a consciousness of the
representation that is immediately before my mind, and that is all (Hume’s
“red here now”). Now it is true that the figurative synthesis alone is not
21
sufficient to determine the content of what is empirically given, and hence,
what specific representation is to be reproduced (for that, something must
be presented to the senses), but it is a necessary condition for such
reproduction, since it anticipates the form in which empirical content must
be given. It is Kant’s insight that if the understanding can anticipate the
form in which intuitions are to be given and work on that, it has a way of
determining, a priori, the relations of the empirically given representations
that must be given through such forms.
It is no accident that all of Kant’s examples in his discussion of the
threefold synthesis in the A-deduction are mathematical and geometrical
ones. For such examples underscore the action of the understanding on the
pure forms of intuition, space and time. Only through such action do I have
an a priori combination of the manifold. And only through the generation of
the figurative synthesis, through my addition of one homogenous unit to
another, can I become conscious of the identity of the act through which the
manifold is synthetically combined a priori. (The figure in space allows me to
apprehend in one and the same act what I constructed successively.) Now,
consciousness of the identity of distinct acts of apprehension just is the
function of the concept. Only through such a consciousness (of the identity
of the act) can I become self-consciously aware of myself as having
representations. Such awareness of myself as having representations is
necessary if I am also to be conscious of how intuitions are given to me
empirically for combination. This is the upshot of Kant’s point at §18 that
both consciousness of how we apprehend representations, as well as
consciousness of our associations, presupposes an objective unity, for only
through such an objective unity can we reproduce and recognize
representations in a concept.
This means that for beings such as ourselves, a figurative synthesis is
a necessary condition for our arriving at an awareness of both ourselves and
of an object that is distinct from us. For other possible beings with a
discursive understanding but not our forms of intuition, some such a priori
22
synthesis of their forms of intuition would be necessary as well, for only
through what it produces a priori can the understanding grasp the identity of
its action. Kant attempts to underscore this point at §18, abstracting from
our forms of intuition.
In bringing in the A-deduction discussion of why the subjective unity
presupposes the objective unity, I have anticipated many arguments that
would only be fleshed out in the second part of the B-deduction, in particular
those having to do with the action of the understanding on the forms of
intuition. These arguments are however, already introduced in § 18, where
Kant not only mentions the dependence of the subjective unity on the
objective unity, but also notes that the form of intuition in time stands under
the original unity of consciousness.
Judgment
In paragraph 19 the distinction between the subjective and the
objective unity is completed. Two important points are made here. First,
the copula “is” in a judgment is that which distinguishes the objective unity
from the subjective unity (B 142). It indicates that a representation is not a
determination of the mind, but of an object.xiv In the judgment the
representation is referred to an object distinct from both the mind and the
representation itself; the representation can agree or fail to agree with the
object, and the intended object of judgment always contains more than any
possible representation of it. Hence in a judgment I distinguish the order of
representations as they occur in my mind (when I pick up the stone I feel
that it is heavy) from the connection of attributes as they are given in the
object (the stone is heavy).
Second, through judgment given cognitions are brought to the
“objective unity of apperception” (B 141). This means that in the final
analysis the object of judgment is structured through the transcendental
object discussed earlier in our analysis of the passage at A. Cognitions are
brought to an objective unity in the concept of the object about which I make
23
judgments. Any object about which I make judgments must have the
structure of a transcendental object, for it must be possible in principle for
me to relate that object to the whole of possible experience. This means the
intentional object about which I judge is an infinite object, relatable in
principle to the whole of possible experience. Any intentional object about
which I make judgments can therefore serve as a focal point, so to speak, to
which I must be able to relate all other possible experiences through
judgments. Only insofar as the object embodies this transcendental
structure, such that all possible experiences can be referred to it, does the
whole of apperception acquire objective unity. It is in virtue of the object of
judgment that all representations can belong to a single apperception, that
is, these representations can belong together in virtue of the structure
xiv Baum makes the important point that it is through the understanding’s
function of bringing representations to an objective unity that the mind is
capable of taking its representations as representations of the
determinations of an object. As such, it is only through the objective unity
that the mind is capable of distinguishing between its having a
representation, and its attribution of such a representation to an object (in a
judgment): “Die Vereinigung alles Manigfaltigen der unmittlebar gegebenen
Vorstellungen erzeugt den bestimmten Begriff eines Objekts und macht
zugleich die im Begriff vereinigten Vorstellungen als Bestimmungen des
Objekts überhaupt auf dieses beziehbar. Der Form der Verbindung nach
beruht also der bestimmte Begriff auf der Vereinigungstätigkeit des
Verstandes, wodurch es allererst möglich wird, Vorstellungen, die doch
Bestimmungen meines Gemüts sind, als Bestimmungen (Prädikate) von
gegenüber meinen sinnlichen Vorstellungsvermögen unabhängigen Objecten
zu denken,” Manfred Baum, Deduktion und Beweis in Kants
Transzendentalphilosophie: Untersuchungen zur Kritik der reinen Vernunft,
Königstein: Hain bei Athenäum, 1986, 119.
24
indicated by the transcendental object determining the synthesis of
representations.
What does this analysis tell us about the possibility of self-
consciousness? Given that the cognitions of possible experience belong
together objectively in virtue of the structure of the object about which I
make judgments, it is this necessary structure of the object (the
transcendental object) that allows me to call them all mine. For given that I
am only conscious of a limited number of representations at a given time, I
can only reproduce and recognize representations as parts of my possible
experience (and hook them up with the representation that I currently have
before my mind) insofar as they conform to the structuring of
representations that I anticipate insofar as I refer them to the transcendental
structure of the object about which I am making judgments. As Baum notes,
this means that any representation given a posteriori can only be related to
an object of representation insofar as representations have already been
connected in the original synthetic unity of apperception, also called the
objective unity of self-consciousness.xv Judgment presupposes a
transcendental object, an object distinct from my representations, to which
my representations are referred. Reference to such an object presupposes
the objective ordering of representations, and in judgment I make explicit
that a representation has been brought to the objective unity. As such, “the
categories are nothing other than these very functions for judging, insofar as
the manifold of a given intuition is determined with regard to them” (B143).
In other words, judgment presupposes the categories, which determine the
object in such a way that judgments of quantity, quality, relation, and
modality can have objective validity. The categories make an objective
order of representations possible, and are thus transcendentally necessary.
As is well known however, Kant’s transcendental B-deduction does not,
as one might expect, end here. In §21 he emphasizes that all that he has
achieved thus far is a specification of the action of the pure understanding
xv Baum, 124.
25
“whose entire capacity consists in thinking,” that is, in synthesizing and
unifying material given to it from elsewhere. Once again Kant brings to the
fore issues peculiar to a pure discursive understanding whose only function
is an active synthesis, and which does not itself produce the matter of its
synthesis. Hence the understanding “cognizes nothing at all by itself, but
only combines and orders the material for cognition, the intuition, which
must be given through the object” (B145). In other words, without the
matter of intuition, nothing determinate is known. Kant distinguishes
between the thinking of an object and the cognition of an object (B146). In
the mere thought of an object, all that is given is its mere logical form, e.g.,
the logical forms for judging that must be presupposed if an object is to be
cognized at all. Here the material that is to be organized through these
logical principles has been completely abstracted. Kant notes that “if an
intuition corresponding to the concept could not be given at all, then it would
be a thought as far as its form is concerned, but without any object, and by
its means no cognition of anything would be possible, since, as far as I would
know, nothing would be given or could be given to which my thought could
be applied” (B146). The problem introduced in §22 is whether, and how, an
intuition corresponding to the concept can be given. How is it possible that a
material given to a faculty distinct from the understanding, namely
sensibility, is at all amenable to the understanding’s activity of synthesis?
Unless it can be shown how intuitions corresponding to concepts can be
given, the activity of the understanding would be pointless, yielding no
knowledge whatsoever. Kant stresses that “our sensible and empirical
intuition alone can provide them [the categories] with sense and
significance” (B149).
Corresponding to the problem that the categories are mere forms of
thought and provide no cognition on their own is the problem that the
activity of the understanding alone is not sufficient to determine the I think,
which is a necessary condition of the possibility of judgment. According to
my reading, the problem driving both parts of the transcendental deduction
26
(the first part concluding in §20, and the second part concluding in §25) is
how an a priori determination of the I think is possible. As such, while at the
end of §20 Kant concludes that the categories are “nothing other than these
very functions for judging,” this does not conclude the deduction, since two
key issues remain outstanding. The second half of the deduction will answer
both a) how it is that intuitions corresponding to the categories can be given
and b) how the manner of the givenness of these intuitions guarantees that
an a priori determination of the I think is possible, a precondition for both
the formation of concepts and for judgment.
What then, is involved in the determination of pure intuition, and how
might the way that it is determined allow us to solve the problem of how an
intuition corresponding to the concept can be given? Key to an answer to
this question is the figurative synthesis, that is, the transcendental synthesis
of the imagination. Imagination, Kant tells us, “is the faculty for representing
an object even without its presence in intuition” (B151). Now, on the one
hand, imagination belongs to sensibility insofar as the original material of the
imagination are the forms of intuition (and in us intuition is always sensible),
namely space and time. On the other hand, imagination is allied with
understanding because through the action of the understanding on space
and time, [“an effect of the understanding on sensibility and its first
application” (B152)], the imagination is spontaneous, namely productive, in
that through its capacity for representing an object without its presence, it
projects the infinite homogenous space and time in which all empirical
intuitions will be given. In a very significant passage Kant notes that
We cannot think of a line without drawing it in thought, we cannot think of a circle without describing it, we cannot represent the three dimensions of space at all without placing three lines perpendicular to each other at the same point, and we cannot even represent time without, in drawing a straight line (which is to be the external figurative representation of time), attending merely to the action of the synthesis of the manifold through which we successively determine the inner sense, and thereby attending to the succession of this determination in inner sense. Motion, as action of the subject
27
(not as determination of an object), consequently the synthesis of the manifold in space, if we abstract from this manifold in space and attend solely to the action in accordance with which we determine the form of inner sense, first produces the concept of succession at all. The understanding therefore does not find some sort of combination of the manifold already in inner sense, but produces it, by affecting inner sense (B154-5).
Here we find the answer to the question posed above: how is it possible that
empirical intuition is amenable to the synthesis of the understanding? In
answering this question Kant notes that the manifold is not combinable
because combination is already found in it, it is, rather, combinable because
in producing the homogeneous bits of space and time in which all empirical
intuitions must be given, the imagination has already produced a
combination of the manifold by affecting both inner and outer sense. Inner
and outer sense, considered by themselves, contain the mere form of
intuition, but without combination of the manifold in it.xvi This combination
occurs through the action of the understanding on the homogeneous units of
space and time, for example, in the case of inner sense, “the action of the
synthesis of the manifold through which we successively determine inner
xvi See R. 6354 where Kant claims “Der innere Sinn is noch nicht Erkenntnis
meiner selbst, sondern zuerst müssen wir Erscheinungen durch ihn haben,
nacher allererst durch Reflexion über dieselben uns einen Begriff von uns
selbst machen, der alsdann empirisches Erkenntnis meiner selbst, d.i. innere
Erfahrung, zur Folge hat” (AA XVII 680). As stressed by both Ameriks and
Mohr, Kant makes a sharp distinction between inner sense and apperception:
“A complete act of apperception is thus meant to contrast sharply with any
mere stream of ‘sense data’. Such data . . . lack cognitive standing . . . and
it is a ‘Myth of the Given’ (as Wilfrid Sellars stressed) to suppose they are
already cognitions, already in the space of reason, justification, putative
truth, or falsity” Ameriks, Kant and the Historical Turn, (Oxford: Clarendon
Press, 2006), 54. Cf. Georg Mohr, Das sinnliche Ich (Würzburg: Königshausen
& Neumann, 1991).
28
sense,” and in the case of outer sense, the drawing of the line. As Kant
notes, it is through the very activity or motion of the subject that the concept
of succession is produced at all, and it is in and through the running through,
reproducing, and recognizing of the succeeding parts of the line/the
succeeding parts of time that these are combined (through the action of the
subject) and are therefore relatable to one another. Importantly, as Kant
notes at B160, the action of the understanding in determining both inner and
outer sense give us the formal intuitions of space and time, in which the
unity of representation is given.
Now, it is because all empirical intuitions must be given through the
forms of space and time, which themselves have already undergone an a
priori synthesis, that such intuitions can (and indeed must) correspond to the
categories. Whatever material is given through the forms of space and time
(and all empirical intuitions must be) will stand under this same synthesis to
which space and time have already been subjected. Hence at §26 Kant
notes that
But space and time are represented a priori not as mere forms of sensible intuition, but also as intuitions themselves (which contain a manifold) and thus with the determination of the unity of this manifold in them…. Thus even unity of the synthesis of the manifold, outside or within us, hence also a combination with which everything is to be determined in space and time must agree, is already given a priori, along with (not in) these intutions, as a condition of the synthesis of all apprehension (B160/161).
In other words, only given the prior unity of the forms of intuition (given
through the action of the understanding on the forms of intuition) is
empirical apprehension even possible at all. As noted earlier, apprehension
(where the manifold is run through and held together) presupposes the
reproduction and unification of the reproduced with that which was grasped
a moment before. Without the capacity to reproduce and unify a priori, just
as I would always be dropping out the preceding parts of a line, so also I
29
would be dropping out the preceding parts of space and time in which
empirical intuitions are given, and as such, I could never apprehend at all.
Corresponding to the problem that all that has been accomplished up
until §20 is the determination of the necessary synthesis of the
understanding “whose entire capacity consists in thinking” and which
“cognizes nothing at all” by itself, is the fact that the first part of the
deduction still has not shown us how determination of the “I think” is
possible. As Kant notes at §24, the synthesis of the understanding
“considered in itself alone, is nothing other than the unity of the action of
which it is conscious as such even without sensibility” (B153). The character
of this consciousness is discussed at §25, where Kant notes that
In the transcendental synthesis of the manifold of representations in general, on the contrary, hence in the synthetic original unity of apperception, I am conscious of myself not as I appear to myself, nor as I am in myself, but only that I am. This representation is a thinking, not an intuiting (B157).
Now, the consciousness that I am is a function of the activity of the
understanding alone, namely of the synthetic original unity of apperception
in abstraction from its action on our determinate forms of sensibility.
Through it the self is immediately aware of its activity, and as such of its
existence, but through it alone it cannot become conscious of itself or make
itself its own object, that is, achieve self consciousness. Without a
determinable sort of intuition, no determinate cognition, and as such, no
determinate cognition of the self as the “I think” that endures through time
(and hence as the self that is determined as the same I throughout all
changes in its representational states) is even possible at all. In other words,
without such a capacity for self-consciousness, it is impossible for me to re-
identify the I that thinks a given representation now with the I that thought
the same representation a moment before. But without this capacity for the
I to accompany all my representations (and hence a capacity for self-
consciousness) all thinking and judgment would be impossible, for I would
30
not be able to distinguish myself from my representations, let alone attribute
a determination to an object distinct from me.
How then, is such a determinate cognition of the self possible a priori?
Key to the answer to this question is the passage quoted above from B154,
where Kant notes that “We cannot think of a line without drawing it in
thought…and we cannot even represent time without, in drawing a straight
line (which is to be the external figurative representation of time), attending
merely to the action of the synthesis of the manifold through which we
successively determine inner sense, and thereby attending to this succession
in inner sense.” The capacity to think the I as identical throughout the
changes in its representational states is necessary for self-consciousness.
Now, in order to think this identity of the I, the synthetic unity produced by
the pure understanding alone is necessary but not sufficient. It is this
synthetic unity that has been arrived at in §20. The pure understanding
produces rules determining the necessary relations of representations to one
another (valid for any understanding whatsoever), thereby yielding a unity of
objective experience. But while this may guarantee a unity of experience,
this is not a cognition of an x that remains identical throughout the changes
in its representational states. In order for the self to represent itself as that
which remains the same throughout the action of its synthesis of the
manifold, it must be possible for it to represent itself as producing the
synthesis while at the same time being conscious of the successive
syntheses produced thus far as the result of its own action. It can grasp
itself as that which remains identical throughout its syntheses in its
representation of its own activity of drawing the line: here the identity of
consciousness is represented by the arrow that remains the same as it
traverses distinct points on the line:
As Kant notes at the very important passage at B 292:
31
Now how it is possible that from a given state an opposed state of the same thing should follow not only cannot be made comprehensible by reason without an example, but cannot even be made understandable without intuition, and this intuition is the motion of a point in space, the existence of which in different places (as a sequence of opposed determinations) first makes alteration intuitable to us; for in order subsequently to make even inner alterations thinkable, we must be able to grasp time, as the form of inner sense, figuratively through a line, and grasp the inner alteration through the drawing of this line (motion), and thus grasp the successive existence of ourself in different states through outer intuition; the real ground of which is that all alteration presupposes some thing that persists in intuition, even in order merely to be perceived as alteration, but there is no persistent intuition to be found in inner sense.
For this a priori cognition of the self, both space and time are necessary, for
only through the action of the understanding on the a priori forms of intuition
is the self able to represent itself and the results of its activity to itself. As
Kant clearly recognizes, this means that for the self to be able to represent
to itself the successive syntheses produced thus far as the result of its own
action, inner sense is not sufficient:
….time, although it is not itself an object of outer intuition at all, cannot be made representable to us except under the image of a line, insofar as we draw it, without which sort of presentation we could not know the unity of its measure at all, or likewise from the fact that we must always derive the determination of the length of time or also of the positions in time for all inner perceptions from that which presents external things as alterable; hence we must order the determinations of inner sense as appearances in time in just the same way as we order those of outer sense in space….
In other words, I can only represent the unity of the successive acts of
syntheses insofar as I can apprehend and recognize them all together
simultaneously in one manifold, but in order for this simultaneous
representation to be possible, I must represent them altogether in space as
the points of a line. The I that remains identical throughout both its distinct
acts of syntheses and the changes in its representational states is
represented as
32
the forward arrow of the line (representing the motion of the point) that
remains continually in motion. Moreover, through the representation of its
activity of drawing the line, the self projects itself into the future.
This a priori determination of the I think, possible through the
figurative synthesis (namely the a priori action of the pure understanding on
the forms of intuition), must be distinguished from both the empirical self
and the self of apperception. The empirical self is given only through
experience; as noted at the beginning of the paper, it is dispersed and
continually changing. It will not supply the unity and identity required for us
to be able to represent the I think to ourselves. On the other hand, as Kant
notes, while I can become immediately aware of the I of apperception, this I
of apperception cannot be an object of my awareness. Just as the eye
cannot see its own seeing, the I cannot apperceive its own action of
apperception. It can, of course, apperceive the results of its past acts of
synthesis and apperception. But in order to cognize them, it must set these
results of past syntheses in relation to one another, and this is an action that
the understanding performs on its own past acts of synthesis. As such, the
self that is given in inner sense, that is, the self that has become its own
object is the product of self -affection, and it must be strictly distinguished
from the I of apperception. This is what Kant means when he notes that
“This presents even ourselves to consciousness only as we appear to
ourselves, not as we are in ourselves, since we intuit ourselves only as we
are internally affected, which seems to be contradictory….” (B153).
Kant poses one last question, namely, given that the I of apperception
and the self that intuits itself differ, how are we to understand that the two
are identical? He asks:
But how the I that I think is to differ from the I that intuits itself (for the I can represent other kinds of intuition a at least possible) and yet be identical with the latter as the same subject, how therefore I can say that I as intelligence and thinking subject cognize myself as an object that is thought, insofar as I am also given to myself in intuition, only, like other phenomena, not as I am for the understanding but rather as I appear to myself, this is

no more and no less difficult than how I can be an object for myself in general and indeed one of intuition and inner perception (B155).
Self-consciousness, and thereby the capacity to intuit oneself,
presupposes awareness of an identity between the self of apperception (the I
as thinking, of which we have only an immediate awareness) and the I that
has become its own object. Self-reflective awareness of myself implies an
understanding of the self as enduring through time, and this means as
enduring throughout changes in its representational states. These changes
must be brought together and synthesized in order to be thought of as the
representations of a single subject. As noted above, this self-awareness
presupposes that I can represent myself in accordance with the following
analogy: just as the moving point remains identical throughout changes in
its position, so the self can be thought of as remaining identical throughout
the changes in its representational states. However, the ‘I’ that has become
its own object not only relates past acts of syntheses to one another (and so
synthesizes the syntheses), it must also recognize these past acts of
synthesis as products of the same I that is now active in apprehending them.
How it is that such recognition occurs lies at the heart of the irreducible and
mysterious character of subjectivity itself.
